iio: mxs-lradc: fix iio channel map regression
commit 03305e535cd5cdc1079b32909bf4b2dd67d46f7f upstream.
Since commit c8231a9af8147f8a ("iio: mxs-lradc: compute temperature
from channel 8 and 9") with the removal of adc channel 9 there is
no 1-1 mapping in the channel spec.
All hwmon channel values above 9 are accessible via there index minus
one. So add a hidden iio channel 9 to fix this issue.
